Socket Key Proline Gala 1/2" 6-point 22 mm

Proline Gala socket key 1/2" 6-point 22 mm is a hand tool for fastening and loosening hex fasteners. The 22 mm, 6-point head fits 1/2" drive tools and is intended for automotive, machinery maintenance and general workshop use. Manufactured from chrome‑vanadium steel and subjected to a controlled hardening and tempering process, this socket offers consistent hardness and durability while ensuring accurate torque transfer and secure engagement with fastener heads.

Advantages

The socket is made of chrome‑vanadium steel and heat-treated to meet high strength and wear resistance standards; its mechanical properties exceed DIN 3124 and PN‑ISO 1711 requirements. The 6-point profile with PRO‑DRIVE specially profiled edges reduces point loading on fastener corners and helps prevent rounding of hex heads, improving contact and torque transmission.

Suitable for

• Automotive repairs and maintenance
• Machine and equipment servicing
• General workshop and professional DIY tasks
• Use with 1/2" drive ratchets, extensions and torque wrenches

How to use

Select the 22 mm, 6‑point socket and attach it to a compatible 1/2" drive tool such as a ratchet, extension bar or torque wrench. Engage the socket fully onto the fastener head before applying torque. When loosening seized bolts, apply steady, controlled force and avoid sudden jerks. For tightening, follow the specified torque values for the fastener and tool in use.

Usage recommendations

Store the socket clean and dry after use, avoid using the socket with impact tools unless it is specifically rated for impact use, and inspect regularly for wear or rounding—replace if deformities are found to maintain safe and accurate torque transmission.
